<p>PURPOSE:To facilitate the size control of an eccentric cam by setting a direction changing cam reception tube to the vertical or horizontal attitude interlockingly with the normal or reverse rotation of an eccentric cam, vertically or horizontally reciprocating the direction changing cam reception tube at the respective attitude positions, and linearly or rockingly reciprocating an operating body. CONSTITUTION:An eccentric cam 29 is interlockingly connected to the output shaft 21 of a motor 13, the eccentric cam 29 is slidably coupled with the elliptic opening 31 of a direction changing cam reception tube 30, the direction changing cam reception tube 30 is rotated interlockingly with the normal or reverse rotation of the eccentric cam 29 by the preset angle, and it is selectively set to the vertical attitude or the horizontal attitude. The direction changing cam reception tube 30 is vertically or horizontally reciprocated according to the normal or reverse rotation of the eccentric cam 29 at respective attitude position, and an operating body is linearly or rockingly reciprocated. A motion direction changing cam section uses only one eccentric cam 29, thus the size control of the eccentric cam 29 in the parts production stage is facilitated, and the motion direction changing cam section can be manufactured at a low cost.</p> |
